PROCESS FOR PREVENTING DECOMPOSITION OF HYDROGEN-PEROXI'D SOLUTIONS.

No Drawing.

To all whom it may concern:

Be it lmown that I, Dr. 'ANnRnAs FAnaeo, residing at Budapest,1n the Empire of Austria-Hungary, at the time at Berlin, Germany, have invented certain new and useful Improvements in Processes for Preventing Decomposition of Hydrogen-Peroxid solutions, of which the following is a specification.

The subject of the present invention is a process for preventing decomposition of hydrogen-peroxid solutions.

It has been discovered that hydrogenperoxid solutions, which otherwise in any circumstances decompose by forming water and oxygen, do not sufler from decomposition in closed receptacles which contain oxygen under high pressure. This discovery forms the basis of the present invention, which essentially consists in saturating hydrogen-peroxid solutions with oxygen and subjecting the so-obtained solutions to high gas pressure in hermetically 'closed recep-.

tacles. These solutions remain permanently in this condition without decomposition and their content of hydrogen-peroxid undergoes no change whatever.

The process according to the present invention is based on the law of mass-action, according to which the increased concentration of one of the components of reaction alters the equilibrium of the reaction in the sense, that the concentration of the resulting product of reaction decreases to the The process may be performed in various Specification of Letters Patent.

ways. It will only be necessary to take care that the hydrogen-peroxid solution, saturated under suitable pressure with oxygen,

be forced under thesame amount of pressure into a closed receptacle. Hydrogenperoxid solution may then be drawn therefrom in any desired quantities.

According to one method of carrying out the process, which answers the purpose, the hydrogen-peroxid solution, after being saturated with oxygen is filled under pressure into siphon bottles.

The appliances to be used in the execution of both phases of the process, viz: the saturation and the filling are identical with those employed in the manufacture of soda Water, with the exception however that their
